Product details

2.64V threshold supervisor for a single rail

The TPS3809L30DBVT is a Texas Instruments simple reset/power-on reset IC monitoring a single voltage rail with a threshold of 2.64V. The active-low, push-pull output asserts reset when the monitored supply drops below that threshold and holds it for a minimum of 120ms after the rail recovers. This part is typically specified by hardware engineers who need a clean, deterministic reset pulse for a 3.3V or 3.0V microcontroller, FPGA, or SoC without extra features like watchdog or manual reset.

Frequently asked questions

What is a direct replacement for TPS3809L30DBVT?

The TLV803EA29VDBZR is a functional peer with a similar reset type (active low) and a 130ms minimum reset timeout, but its output is open drain/open collector rather than push-pull, and its operating temperature range extends to 125°C. The TLV803ED29DBZR offers a 33ms minimum timeout and open-drain output. Neither is a pin-for-pin drop-in without checking the output type and timing differences.
